SASH-COBD-FASTENING DEVICE.

Specification of Letters Patent.

Patented Nov. 25,1913.

Application fil ed October 8, 1912. SeriaI N 0. $724,645.

connection between the sash cord, the fastening device and the sash, whereby th cord may be readily attached-to and dc tached from the fastening device without the raising or lowering of ears or projections and whereby the fastening device may be readily attached and detached from the sash without the use of ,a metal socket :device or the use of ears or projections but which sustains the weight without danger of splitting or marring the sash and which can be readily and quickly detached from the sash whenever it becomes necessary or desirable to remove-it.

With these and other objects in view my invention consists in a combination of parts and arrangement of parts as wlll be ,her einafter more fully described, shown .in the.

accompanying drawings and particularly pointed out in the appended claims, it being understood that changes in the proportion, size material, metal and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

Referring to the drawings, Figure 1 is a detail perspective view of the fastening device for application to the end of a sash cord, and shows the detail parts thereof. Fig. 2 is an elevation of a window sash equipped with a sash cord fastener embodying this invention. Fig. 3 is a central, longitudinahsectional view showing one corner portion of a window sash, equipped with the sash cord fastening device and showing the manner of insertion of the sash cord to the fastening device. Fig. 4 is a central, longitudinal sectional view of the fastening device. Fig. 5 is a detail and similar view of the fastening device showing the beveled or thickened edge of the circular head thereof.

Referring to the drawings, the letter W designates the upper corner portion of a window sash which is provided in its vertical edge with the usual cord groove G and circular groove, recess or seat R at the lower end of said groove, to receive the anchoring device for thecord.

The fastening device which is app ied to the end of the sash cord consists of a laterally-bowed shank portion A which has one end, which is normally'its lower end, provided with an enlarged circular head 13 that lies in substantially the same plane with the shank and is-connected thereto by means of a reduced neck portion, the oppo-,

site edges of the shank being bent so as to form ,a trough in which the cord 0 lies. The width of (the shank is substantially the same as that of the reduced neck. The shank portion is provided with two rough edged perforations D and v E respectively, so as to take in the .cord G.

In carrying out the invention that portion of the shank lyingbetween the perforations .-D and E, that is, F is .pressed inward. it will :be observed that in perforating the shank at D and E it leaves the edge of the circular holes rough and by placing the cord C'through D through the trough and then through 'E, F becomes a bridge or binder which keeps the cord from slipping from the fastener and does away with the necessity of ears, projections and spurs. The edge of the circular head H is beveled thereby doing away with the necessity of a metal socket to prevent its marring or splitting the sash. It will be further observed that the fastening device is inserted into the groove G and that the circular head is inserted into the socket R in such a manner that the circular head rests against the foot of the socket and that the cord 0, as it passes beneath the bridge F, rests against the bottom of the groove G. The weight of the sash causes the top edge of B to press firmly against the top of the socket R and holds B firmly in place without the necessity of spurs, projections or wings or fasteners of other kind. By this means the cord may be conveniently applied to and removed from the sash without damage to any of the parts and does not require the removal of other fastening devices or the raising or clamping of ears, projections or spurs.

The advantage of the present form of sash cord fastening device lies in the fact that the beveled edge of the circular head B does the socket recess or seat R to prevent the marring or splitting of the sash and that the circular head B being inserted deeply in the socket, recess R, and the strain of the weight of the sash falling upon the upper edge causing C to pull outward from the sash against said top of the circular head causes the circular head B to remain in the socket R and the bowed shank A to remain in the groove G without the necessity of projections, spurs, or ears. Finally the fastening device may be struck from a blank of metal, then the shank bent into the form of a trough, the perforations D and E made, the bridge F bent into the form of an inverted shank thereby providing a strong, desirable and inexpensive form of sash cord 7 fastening device.

What I claim as my invention and desire to secure by Letters Patent is 1. In a device of the class described,awindow sash, a groove in the vertical edge thereof, adapted toretain a cord, a recess at the bottom of said groove being circular in 7 form and wider and deeper than said groove,

a shank adapted to fit in said groove, a head to said shank wider than said groove and adapted to fit deeply and in an inverse position in said recess, a portion of said shank bent upwardly forming a bridge, the shank and circular head adapted to be held in place by the outward trend of the cord and the pressure of the upper part of the circular head against the upper walls of the recess and adapted to hold the cord in place by the friction of the cord passing over the bridge, without projections, spurs or cars, a beveled edge to the circular head adapted to prevent the marring or splitting of the wood of the sash.

I 2. In a device of the class described, a window sash having a groove in the vertical edge thereof, a recess in said sash at the bottom of said groove, wider and deeper than said groove, a laterally bowed shank adapted to fit in said groove, the lower end of said shank forming a circular head, flat in form and broader than said groove and adapted to fit in said recess, a portion of said shank bent upwardly forming a bridge, the said circular head adapted to be inserted deeply in said recess whereby the strain of the weight of the sash falls upon the upper edge and causes the cord to pull outwardly from the sash against said top of the circular head causing the circular head to remain in the socket and the bowed shank to remain in the groove Without the necessity of projections, spurs or ears, adapted to hold the cord in place by the friction of the cord passing over the bridge.

In testimony whereof I do hereby affix my signature in presence of two witnesses.
